Probability-Based Sensitivity of Service Life of Chloride-Attacked Concrete Structures with Multiple Cover Concrete Repairs

Estimating Residual Service Life of Deteriorated Reinforced Concrete Structures

Evaluating present condition of reinforced concrete (RC) structures is necessary for planning future maintenance and estimating residual service life of structures. A ten point (0-9) condition rating system is proposed for obtaining present condition of RC structures based on the measured values of concrete cover, carbonation depth and chloride concentration at rebar depth through in-situ tests...

Validation model for service life prediction of concrete structures

Most bridges in the highways of the Netherlands are designed to last 80 years. In those 80 years only minor damage should be repaired. To determine the repair strategy of these minor damages the so-called Lifetime Extending Maintenance model can be used. This model is a condition model, which has been used for many materials like paint on steel [1]. In this paper we will show an application of ...

Computational methods in service life modeling of concrete structures

Reinforced concrete (RC) Structures constructed over six decades ago are now approaching the end of their service life and showing serious level of deterioration and therefore, prediction of service life of structural materials and components has gained significance. With the increased efforts of researchers, development in computer knowledge and advancement in building materials science, it is...

Hierarchical Life-Cycle Design of Concrete Structures

Concrete structures’ service life lasts decades. In order to deal with all the probable degradations and deteriorations in the whole life span, the concept of concrete structures’ Life-Cycle Design was introduced into China in the 1980s. However, until this day, Life-Cycle Design is still more of a concept to most structure designers and engineers, rather than a practical method. This paper pro...
